       4. The radiometric measuring device according to  claim 3 ,
 wherein the first fastening element and/or the second fastening element is/are provided from a common distal end of both tubes to a distal end of the source receiving tube, 
 wherein the first fastening element is provided from a common distal end of both tubes to a distal end of the source receiving tube, and 
 wherein the second fastening element is provided from a common distal end of both tubes to a distal end of the transmission tube. 
 
     
     
       5. The radiometric measuring device according to  claim 4 ,
 wherein a second fastening element is provided between the source receiving tube and the transmission tube, the second fastening element being connected to the source receiving tube and the transmission tube in longitudinal extension so that both tubes are arranged spaced apart from each other, 
 wherein the first fastening element and the second fastening element are arranged at least partially opposite each other in longitudinal extension, 
 wherein the second fastening element is formed as a second retaining sheet metal element, and 
 wherein the tubes are each connected to the second retaining sheet metal element by means of a welded joint. 
 
     
     
       6. The radiometric measuring device according to  claim 5 , wherein the first fastening element and the second fastening element are arranged opposite each other in longitudinal extension up to a distal end of the transmission tube, such that a cavity is formed between the first and the second fastening elements, the cavity being closed by means of a cover element. 
     
     
       7. The radiometric measuring device according to  claim 1 ,
 wherein the source receiving tube and the transmission tube are connected at one of their end faces to a flange element, 
 wherein the connection is provided by means of a welded joint, and 
 wherein the flange element is configured to be connected to a correspondingly formed flange element of a container on which the radiometric measuring device is arrangeable. 
 
     
     
       8. The radiometric measuring device according to  claim 1 ,
 wherein the source receiving tube has a smaller wall thickness than the transmission tube, and 
 wherein the source receiving tube has a smaller diameter than the transmission tube. 
 
     
     
       9. The radiometric measuring device according to  claim 4 , wherein the first fastening element and/or the second fastening element have different wall thicknesses in longitudinal extension. 
     
     
       10. The radiometric measuring device according to  claim 3 , wherein the first fastening element is adapted in longitudinal extension to a curved course of the source receiving tube. 
     
     
       11. The radiometric measuring device according to  claim 4 , wherein the first fastening element and/or the second fastening element are provided as an edge part or as a surface part. 
     
     
       12. A radiometric measuring device, comprising:
 at least one at least partially bent source receiving tube configured to receive a radiation source; and 
 at least one transmission tube configured to provide a guiding path within the transmission tube for at least a portion of the radiation emitted by the radiation source, 
 wherein the source receiving tube and the transmission tube are arranged relative to each other such that at least a portion of radiation emitted by the radiation source is guidable in a straight line through a material disposable between the radiation source and a distal end of the transmission tube and the guiding path, and 
 wherein the source receiving tube is received in the transmission tube, and 
 wherein at least one reinforcing member is at least partially disposed at the source receiving tube. 
 
     
     
       13. The radiometric measuring device according to  claim 12 ,
